BACK-BAND-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 714,012, dated November18, 1902. Application filed May 3, 1902. Serial No. 105.746. (No model.)

To all whom, it may concern:

Beit known that I, GEORGE WILLIS Mo- BATH, a citizen ofthe UnitedStates, residing at Meridian, in the county of Lauderdale and State ofMississippi, have invented certain new and useful Improvements inBack-Band Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates tota machine for cutting, folding, creasing, androlling cloth or other material for back-bands, such as are commonlyused in harness-making.

The general object of the invention is the construction of a device bywhich these various operations will be rapidly and automaticallyaccomplished by one machine.

The invention comprises a suitable frame, upon one end of which iscarriedaroll of the material to be operated on. Mounted upon the frameare the cutting, folding, and creasing devices and means for feeding thematerial to be worked to said devices. Upon the opposite end of theframe are mounted rollers to receive the strips after they have passedthrough the machine.

In the accompanying drawings, illustrating the preferred embodiment ofmy invention, Figure l is an elevation of the complete machine, partlyin section. Fig. 2 is a plan View of the machine. Fig. 3 is a detailView of a friction feed device. View of the underlayer-guide. Fig. 5 isa detail view of a cuttingknife- Fig. 6 is a View of one of thecutting-knives looking in the direction of the arrow in Fig. 5.

In the views, A represents asuitable frame, which may be made of wood ormetal. Upon the lower portion of each side of the frameis rigidlysecured a bar B, which projects beyond the ends of the' frame, andbetween the fore ends of the bars is secured in suitable bearings aroller C. Mounted in bearingplatesD is asecond roller d, located abovethe roller C on the front end of the frame A. In

the rear of said roller d and extending transversely across the frameare the tensionboards e e', the latter being positioned above the formerand held in place by set-screws Fig. 4. is a detail e2, havingtension-springs e3 located between the set-screws and the upper face ofthe board e'. Running transversely across the frame adjacent to thelower tension-board is the slot F, on the opposite side of which andparallel to the tension-board is the cutting-board F', and slidablysecured in said slot are plates F2, their projecting upper portionssliding on one side in a recess formed between the tension-boards andthe frame and on the other side on the upper face of 'the cutting-board,their lower portions engaging flange-like the under surface of theframe. They are thus securely held against vertical movement, while asuitable thumbscrew F3, Figs. 5 and 6, clamps them against horizontalmovement in the slot F. Rigidly secured to each of the plates F2 is acutting-knife F4, projecting upwardly and rearwardly, with its cuttingedge toward the front of the frame. Mounted in bearings upon the mainportion of the forward part of the frame is a shaft G, upon one end ofwhich is a driven pulley G', Fig. 1, and upon the other end asprocket-wheel G2. Intermediate of the two the shaft is enlarged toforma feedroller G3, above which is a second roller G4, mounted in ahinged frame G5 and normally resting on the roller G3, the hingedbracket adapting it to be lifted when the material is to be inserted.From these rollers extend rearwardly parallel folding boards H, equal innumber to the number of strips to be cut. Positioned on these boards arefunnel-shaped folding devices H', having their larger open ends towardthe knives. In the rear of the smaller open end of these and 'adjustably clamped upon blocks H2, which are positioned alongside the pathof the folded material, are the underlayer-guides H3, consisting of armsprojected over the path of the cloth and having their free ends curvedupward. At the rear end of each folding-board are adjustable gagesbetween which the folded material passes on its Way to thecreasing-rollers .I J. These latter are mounted in ahinged bracket J2,and in the rear of them is mounted a small guide-roller corresponding tothe roller d at the frontof the frame.

Between the rear ends of the arms B is hung or journaled a roller orshaft C', corre- IOO spending to the roller C at the front end of themachine. This roller or shaft is grooved longitudinally to within a fewinches of one of its ends, and reels C2, having radiating arms C3, areslipped upon and secured to said shaft by means of lugs projecting fromthe inner surface of the hollow sleeve or hub of each of said reels. Thecut and folded strips are wound upon these reels. Upon one end of theroller K is also mounted a sprocketwheel K. The roller J is alsoprovided with a sprocket-wheel L, the Wheels K and L being upon the sameside of the machine as the sprocket-wheel G2. A sprocket-chain M passesover the wheel G2, thence over L, thence over K, and back to G2, allthese wheels being driven by said chain.

Extending downwardly from the hinged brackets are rods N, connected by acrossbar 0, to which are att-ached springs P, their lower ends beingsecured to the base of the frame, this arrangement serving as a tensiondevice for the feeding and creasing rollers.

By means of a suitable friction feed of any preferred form-such, forinstance, as illustrated, consisting of cone K2, spring K3, and nutK4-the speed of the roller or shaft C may be varied as desired inwinding the folded strips.

In practice the application of the device is as follows: The bolts orrolls of cloth or other material to be operated on being suitably hungor journaled between the ends of the bars B at the forward end of theframe, the free ends of said rolls of cloth are cut or slit to thedesired width for a suitable length by hand and drawn up over the rollerd, inserted between the tension-boards and the feed-rollers, the rollerG4 being raised from contact with the roller G3 bylifting the hingedbracket G5. The cut strips are then passed through the folder H',between the creasingrollers, the upper rollerbeing lifted back by meansof its hinged bracket, passed over the guide-roller J3, and secured tothe reels C2 in any suitable manner. The thumb-screw e2 is now tightenedas much as may be required by reason of the thickness of the material inorder that it may present a smooth surface to the cutting-knives, andpower being transmitted from any suitable source to the pulley G' thevarious operations are rapidly and automatically accomplished.

It is obvious that various minor changes may be made in the inventionwithout departing from the spirit thereof, and I wish it to beunderstood that I do not'limit myself lo details as described herein.

Having thus described my invention, what I claim as new,and desire tosecure by Letters Patent, is-

1. In aback-band machine,the combination with a suitable frame carryingfeed-rollers, cutting-knives mounted transversely across the frame,funnel-shaped folding devices in the rear of said knives,underlayer-guides, creasing-rollers, adjustable gages, reels forreceiving the cut strips, and means for feeding the material to beoperated on to the ma- `chine.

2. Inaback-baud machine,thecombination with a suitable frame, a rollerpositioned at the front of the frame to hold the material to be actedon, a plurality of adjustable cuttingknives mounted on the frame,folding and creasing devices mounted in the rear of the knives,feed-rollers adapted to draw the material to the knives, a rollermounted in the rear of the frame and carrying a plurality of spoolshaving radiating arms and adapted to receive the cut and folded stripsand a common sprocket-chainextending from the feedrollers and actuatingthe creasing and winding devices whereby uniformity of movement issecured between the various parts.

3. In a back-band machine,the combination with a suitable frame, ofcutting, folding and creasing devices mounted thereon, a materialholdingroller, a roller carryinga plurality of reels at the rear of the frame,friction feedrollers, a pulley mounted on the end of one of saidfeed-rollers, asprocket-Wheel mounted at 'the opposite end,corresponding wheels on the creasing device and reel-carrying roller anda common sprocket-chain for the three sprocket-wheels.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE WILLIS MCBATH.
